Several hotels surrounding MetLife Stadium, the site of Super Bowl XLVIII, received envelopes containing a suspicious white powder, causing a scare just two days before the big game.

Ross Levitt and Shimon Prokupecz of CNN report hazardous materials teams and a bomb squad were called to the scene. Law enforcement officials also noted a similar situation in neighboring New York involving a letter sent to the office of Rudy Giuliani.

Jeanne Baratta, chief of staff at the Bergen County Executive's Office, told CNN that an unidentified substance was delivered to a hotel in East Rutherford and two hotels in Carlstadt.

Based on the initial investigation, law enforcement also said the situation is not considered a major threat at this time, according to the report. The FBI was monitoring the situation, though.

Noah Cohen of NJ.com passed along a statement from New Jersey State Police:

The Joint Terrorism Task Force and Hazard Materials units have responded to several locations that have received a suspicious letter and substance. There are no reported injuries at this time, and the locations are being secured.

Given the breaking nature of the situation, it's still unclear exactly how many letters were sent and if more hotels will find similar envelopes. CNN states six letters were found in New Jersey, and NJ.com reports seven locations could already be involved. No injuries were reported.

ESPN reported that the substance in the letters isn't toxic, according to preliminary tests.

Cohen reports the letters that have been found were isolated and are awaiting further investigation by police and the hazardous material teams. As of now, there's been no evacuations at either the Courtyard at Marriott or the Quality Inn, two of the hotels involved.

Further details about the substance and the investigation were not immediately provided by police. Obviously, all law enforcement officials are on high alert for any type of suspicious activity with the Super Bowl being played in the area this weekend.
